The Mobile World Congress doesn't need a introduction.

In the months before the Congress, three developers from Fewlaps joined the Opentrends mobile team to help them achieve the goal: develop the official app of the GSMA's Mobile World Congress 2014.

The app included amazing features like indoor geolocation using Bluetooth 4.0 beacons, a 3D map to guide the user through the Congress, a way to order and pay food in the restaurants of the venue, check the taxi queue online, and of course, the features you expect: a way to know the Congress' expositors, speaks, a way to meet potential partners and so.
